Didn't you try this like a month ago? I still think your Fallout 3 tribute is rather... beginner, and with Pinnacle Studio HD you should be able to do quite a bit better. However the Kragenir's trailer was quite a drastic improve. Albeit still simple cuts and pans, the way they were lain out it look pretty darned good. Kudos on that.
Anyway, In several months my mod will be to the stage where I will start making trailers, as I agree more mods need them. I have 2 planned out I am going to do myself later on. But if you want, when the time comes you can put together a compilation of a bunch of clips of fighting, and some of the action scenes (I will have several scripted ones in the mod) and stuff like that to pull people in. While my 2 focus more on the story of it, yours can be of the gameplay and fighting. Keep working with it, and try more and more complicated things. I hope you get even better (as the is a LARGE improvement between the FO3 tribute, and the death mod thing) when I am ready for you to make my trailer. I will contact you later on when the time comes (probably not till like late april, early may, depending on how fast I work :/) to make one
